Question

我正在将Qt5，VTK，PCL和PDAL编译成一个项目，我的构建过程非常有效，直到我重建PCL，因为我试图摆脱另一个奇怪的错误，在链接后语法错误在Qt5中不断出现PCL。有关详细信息，请参阅此处：Qt, VTK, PCL, and PDAL integration 我最近还同意在root下使用新的XCode许可证。所以这也可能是问题所在。这是确切的错误：

有谁知道为什么我在重建VTK和PCL后似乎无处可寻？谢谢！

在OS X上将PCL拉入QT5时会出现同样的问题。

从源代码编译PCL 1.8解决了该问题（从PCL 1.6迁移）。

的CMakeLists.txt：

project(LRS_PCL)
set(CMAKE_C_COMPILER "/usr/bin/gcc")
set(CMAKE_CXX_COMPILER "/usr/bin/g++")
cmake_minimum_required(VERSION 2.8)

set(SOURCE_DIR .)
set(SOURCE
   ${SOURCE}
   ${CMAKE_CURRENT_SOURCE_DIR}/main.cpp
   PARENT_SCOPE
)
aux_source_directory(. SRC_LIST)
add_executable(${PROJECT_NAME} ${SRC_LIST})
set(CMAKE_PREFIX_PATH $ENV{HOME}/Qt/5.5/gcc_64)

find_package( PCL 1.8 REQUIRED )
find_package( Qt5 REQUIRED COMPONENTS Widgets Core )

include( CheckCXXCompilerFlag )
set( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11" )

include_directories( ${PCL_INCLUDE_DIRS} /user/local/include )
link_directories( ${PCL_LIBRARY_DIRS} /usr/local/lib /usr/lib/x86_64-linux-gnu )
add_definitions( ${PCL_DEFINITIONS} )

target_link_libraries( LRS_PCL ${PCL_LIBRARIES} /usr/local/lib/librealsense.so )
